Document Type and Number:

WIPO Patent Application WO/2020/153422

Kind Code:

A1

Abstract:

This coated titanium material comprises a titanium material and a coating film formed on the surface of the titanium material, wherein: a Ti-based oxide is present at an interface between the titanium material and the coating film; the Ti-based oxide is either or both rutile TiO2 or/and Ti2O3; and when a cut surface of the coating film is formed by using the SAICAS method under the conditions in which the horizontal velocity is 2 μm/s and the vertical velocity is 0.1 μm/s, the area percentage of the Ti-based oxide is 30.0% or more in a region, on the cut surface, ranging from a reference line specified based on a boundary line, which is the intersection line between the cut surface and the interface, to the coating film side by a distance of 15 μm.
